Application filed January 28, i921.

To all 'whom it may concern Be it known vthat I, CLAUDE L. COMER, a citizen of the United States, residing at Santa Ana, in the county of Orange and State of California, have invented certain new and useful Improvements in Plows and Subsoilers, of which the following is a specilication.

This invention relates to plows and more particularly to subsoilers and the like.

The primaryobject of the invention is the construction of a subsoiler which is capable of operation at a predetermined depth and one in which the standards and plow points may be removed without raising'or lowering the frame.

Another object of the invention resides in the provision of a' subsoiler constructed and arranged to independently accommodate hinged standards or a plow attachment, and to rigidly retain the Same in their vertical operative position.

A still further object of the invention is y directed to a novel construction of subsoiler wherein any one plow standard may be raised from the ground without affecting the position of the others or raising the plow frame.

An additional object of the invention relates to an improved and novel form of independent clamping construction for the standards and the plow attachment permitting the same to be locked or unlocked with a minimum of effort and in a highly e'liicient manner.

With these objects in view and others which will be manifest and suggested as the nature andv purpose of the invention are revealed in the following specification and drawings wherein I have shown a practical, yet-.preferred embodiment thereof.

Figure 1 is a plan view of the subsoiler.

'Fig v2 is a side elevation thereof.

Fig. 3 is a vertical longitudinal view in section on the line 3-3 of Fig. 1.

Fig. e is a detached perspective view of one of the standards.

Fig. 5 is a detail view of a plow peint.

'F.ig. 6 is a side elevation of a plow attachment adapted for use in connectionfwith the subsoiler.

Serial No. 440,643.

Fig. 7 is an end view of the attachment shown in Fig. 6.

Fig. 8 is a modified form of a subsoilcr foot and point attached thereto.

lSimilar numerals in the specification refer to like and corresponding parts on the draw ing. The frame of the sub soiler may pret erably be constructed of angle iron and comprises a forwardl)IY extendinrf draft portion 2. sides Z3, l. an angular rear side 5, and a connecting, longitudinally directed center bar lk as shown in Fig. 1. Bent axles 6, 'T are mounted in bearings 8, 9 in the front and rear of the frame and carry theusual ground wheels 10, 11 whereby the machine may be supported for movement.

Cranks 12, 13 are keyed respectively to the front and rear axles 6 and 7 and are connected by a rod 1e so that when the rear and a movable member 17 connected to the rear eank 18 as shown to simultaneously actuate the axles to raise and lower the frame to control the depth to which the plows operate. lft is te be understood, however, that a cylinder provided with a suit able piston and piston rod operated by compressed air, steam. water and other pressure means may be utilized in this connection for raising and lowering the frame and the plow standards and the shovels or mold boards carried thereby.

The side members 3y and et and the inter mediatemember 1 are each formed of two parts 'in spaced relatiom or in pairs. as shown in 'Fig'. 1, and each pair provided with depending perforated ears 19 to receive pivot pins 21, and a stop 33 spaced from the ear.

A 'standard 18 is associated with each beam member and extending by their upper ends 29 between the spaced beam members, and with a rearward extension 18at from each portion 29.

Each standard 18 is likewise provided with an eye 20 to engage between one pair of the ears 19 and receive one of the pivot pins 21. i

Each standard 18 is likewise provided with stop blocks 22 to limit the movement of the standards in one direction.

By this means the standards are free to swing in one direction only.

Shoe members 23 are attached to the lower ends of the standards, and beveled as at 24 and apertured as at 25 to receive holding bolts to enable plow points or shovels 26, or other suitable earth working elements to be removably attached as desired. It will be noted that the plow points are positioned and angularly inclined with respect to the standards which are arranged in staggered relation on the frame, the vdepth of cut being regulated by the height to which the frame is adjusted.

The plow point as shown is formed with a rear extension 26a provided with an aperture 27a which is adapted to register with the apertures 25 whereby the plow point may be securely positioned in the subsoiler foot of the standard. The front cutting edge 28EL of the plow point is preferably in horizontal alinement with the plates 23, said plow point being also provided with an angular projection 29a permitting the soil to ride over the same during the subsoiling.

Inthe form of standard and plow point shown in Fig. 8 the plates 23 are partly cut away to form abutments 30a for the rear extension 26a thus relieving the connecting bolt from the pressure which holds .the plow point inthe subsoiler foot.

The standards 18 are rigidly secured in their vertical, operative position, by means of a locking plate 27, pivoted at 28 with one end engaging the upper extremity 29 of the standards as shown in Fig. 8. By this' arrangement as the plate 27 is moved out of engagement with the standard to the dotted ,line position, the standard may be swung on its pivot 19 by the forward draft and removed from the groiuid to replace the plow point or detach the standard from the frame.

In Figures 5 and 7 a plow attachment capable of use in connection with the device above described is shown and comprises an angularly extending plate 30, in parallel relation to the rear side 5 of the frame on which it bears. The plate 30 is provided with short equally spaced standards 81 and eyes :32 corresponding to the extensions 29 and eyes 2O of the standards 18 to permit attachment of the plate to the pivots 19 of the frame. A plurality of spaced vertical plow standards 32a are se .cured to the plate 30 and adapted to carry any suitable type of plow point, shovel, or other earth working element. By this arrangement the standards 18 may be removed and replaced by the plow attachment 30, 31 and 32a and retained in its operative position by the coaction of the pivots 19 and bars 27.

In the accompanying drawing, I have illustrated my invention embodied in one form by way of example, and which in practice has been found to be highly satisfactory in obtaining the desired results. It will be obvious however that other embodi ments may be adopted, and that various changes in the details of construction may be resorted to by those skilled Vin the art without departing from the spirit and scope of the invention. It is furthermore under-V stood that the invention is not necessarilyy limited or restricted to the precise elements shown except in so far as such limitations are speciiied in the subject matter being claimed.

Having thus` described the inventionfl` extending at the upper end between said`` beam members and hingedly coupled thereto, a rigid stop member between the beam members and spaced from the standard,

and a locking member pivoted intermediate the ends thereof between said beam mem-1' bers and bearing at its ends when in one position against the standard and against the rigid stop member.

2. In an implement of the class described,

supporting beam formed of spaced mem-4 bers inparallel relation, perforated ears depending from said beam members and having a pivot pin extending therethrough, a rigid stop between said beam members and spaced from said ears, a plow standard extending at its upper end between said beam members, a perforated lug carried by said standard and receiving the pivot pin of said ears, and a locking member pivoted intermediate the ends thereof between said beam' members and bearing at its ends when in one position `against the standard and against the rigid stop member.

3. In an implement of the class described,

-a plurality of beams in parallel relation and tending at its upper endrbetween each of said coupled beam members, a stop member between each of said beam members 'and spaced from the standards, and a 'locking member pivoted intermediate the ends thereof between beam members and bearing at its ende when in one position against the standard and against the stop member.

4. In an implement of the class described, a supporting beam, a plow Standard swinging at the upper end upon Said beam, a rigid stop member attached to said beam and spaced from the standard, a looking member pivoted intermediate the ends of said beam and bearing at its ends 4when in 10 ture hereto.
